Returning to the Edinburgh Fringe this year are Marnina Schon and Micah O’Konis. ‘Folk Marry Kill’ is a folktale about sex, death, and the hard question of “how often should a married couple, you know… folk?” We talk about the delights of writing a follow-up show, why “kill your darlings” is something they still have to contend with, and coming back to the Fringe with a little more experience.
